CFast Card Connector Lock Card Structure

The present invention provides a lock card structure of a CFast Card connector, in particular, the two arms of the base of the base body are combined with an elastic positioning member, and the elastic positioning member is used to insert the memory card with low insertion force and high resistance. The pulling force can also be pressed on the elastic positioning member to complete the action of withdrawing the card, thereby achieving the effect of facilitating one-hand operation and repeated insertion and removal.

According to the rapid development of electronic and multimedia technologies, consumer electronic products such as notebook computers, tablet computers, mobile phones, multimedia players, and digital cameras have also grown exponentially year by year, and have become a trend in the new era. Insufficient, and because of the high usage rate of electronic products, it requires multi-functional interface integration and additional services, and users can have a multi-purpose function at the same time.

Furthermore, electronic products for data storage and file management generally use a memory card, especially for single, independent or temporary data storage, and the memory card is inserted into the card connector, and can be realized through the card connector. The communication and processing with electronic products, and the memory card has been widely favored by consumers since its inception, and has become an indispensable tool for use, so the demand for card connectors has also increased significantly.

Since various memory card specifications are different, such as CF card, MS card, SD card, RS-MMC card, etc., there are some differences in the size and shape of the memory, and not A memory card of the same specification must be inserted into a specific card connector that conforms to the type, so that the card connector can access the data inside the memory card, and the CFsat card is a new specification memory card proposed by the CFA (CF Association). The size is the same as that of a normal CF card, but it uses a SATA-compatible interface (the CF card is the IDE interface), so the theoretical limit speed is up to 3Gb/s, and the 133MB/s limit speed is higher than the CF card. It can be used several times faster, in addition to being used as a boot disk, and supports static data reforming and bad block early marking function, so it can repair data, improve data stability and extend service life, and is widely used in industrial computers or other. SATA 3Gb/s devices provide greater performance and convenience.

However, in order to enable the memory card to be smoothly inserted into the card connector with low insertion force, the conductive terminals are generally designed to make the memory card less prone to interference when inserted, and after the memory card is rotated by a certain angle. It is also necessary to further fasten the card to prevent the memory card from being separated from the predetermined position due to the external force. Therefore, the card connector on the market is provided with a locking device, which is made of plastic material. The one-piece molding is also made of metal material. The locking device of the plastic material integrally formed on the insulating body has poor fastening elasticity. If the memory card is inserted and removed multiple times, the locking device is easily deformed or broken. The situation occurs, and the locking device of the metal material assembled on the insulating body has better fastening elasticity, but if it is applied to an industrial computer, a vehicle-mounted computer or other special purposes, it is also affected by external force or body vibration, so that The memory card is easy to jump off or get out of the lock device, or the force of the buckle device is too large, so that the memory card is not easy to complete the card withdrawal. Action, if the user excessive force on the locking device will lead to structural damage or destruction, is not conducive to repeated mating docking use, and to be engaged in this industry, it re-designed to be effectively addressed.

Therefore, the new creators have adopted the problems and lacks of the use of the lock device of the conventional card connector. The collection of relevant materials has been evaluated and considered by many parties, and the trial and development experience of the industry has been continuously tried and modified. A new type of lock card structure for this CFast Card connector was born.

The main purpose of the present invention is that a docking space is formed between the base and the two arms of the base body, and a terminal set is positioned on the tongue plate of the base, and the base of the elastic positioning member and the two side plates are Between the two sides of the base, there is a positioning portion with a spring arm coupled to the corresponding fastening portion of the two arms of the arm, and the two side plates are provided with a locking body at the inner side, when the memory card is When the socket of the elastic positioning member is inserted into the docking space of the base body, the guide rails at the two sides of the memory card are embedded along the corresponding rail grooves on the arm, and are pushed by the plugging portion to the card body. The elastic arm acts as a support to the memory card with a yaw displacement, and after the memory card is inserted into the positioning and electrically connected with the terminal group, the elastic arm of the elastic positioning member can be interlocked through the elastic reset process. The body is locked in the anti-retraction slot of the memory card to form a locked state, and has the effects of low insertion force and high pull-out force, and ensures the stability and reliability of signal transmission.

The secondary purpose of the present invention is that when the user takes out the memory card, one hand can be pressed on the pulling portion of the elastic positioning member, so that the side plates at the two sides of the base can be supported by the elastic arm of the positioning portion toward the memory card. The inner side is in a yaw displacement, and the latching end of the interlocking card body is outwardly disengaged from the retaining groove of the memory card, so that the memory card can be pushed upwards to slide the track of the memory card along the track groove of the arm. Resisting the displacement, and at the same time, the card holder has a suitable elastic resistance against the surface of the memory card, so that the memory card can smoothly complete the card withdrawal operation, and after the memory card is separated from the elastic positioning member, The docking space of the memory card can be quickly taken out from the docking body, thereby achieving the effect of facilitating one-hand operation and repeated plugging and docking, and the effect is less laborious.
